Tatiana Hoover, née Boncompagni, has sued sister Natasha Boncompagni, alleging that Natasha secretly copied parts of the novel and claims co-authorship. The book, which spins a tale of wealthy Wall Street wives, is due to be published next year by HarperCollins.

Hoover, who publishes under her maiden name, acknowledges that her sister provided input for the novel, but never discussed co-authorship until after it was completed. Boncompagni worked at hedge fund Fairfield Greenwich Group, as well as UBS and Citigroup; she claims that the novel’s protagonist, Marcy, boasts a similar work history.

In the lawsuit, filed in Manhattan federal court, Hoover, who published her first novel this year, claims that she was the sole author of the novel, and seeks copyright protection for it. She accuses her sister of copying parts of the book, which was delivered to her publisher last month.

“This was a private family matter that my sister has decided to make public,” Boncompagni said in a statement. “Our entire family is deeply saddened by her decision to willfully misrepresent herself as the sole author of Hedge Fund Wives, a book that we co-wrote.”

Boncompagni says she had planned to sue her sister, but that Hoover beat her to the courthouse.
